Thanks Ilja You shouldn't have to symlink anything unless it tells you to in the book. If you do have to then you need to go back and figure out what's wrong before going any further. You should go back to the gcc installation in chap. 6, and redo that and everything after that. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

I fixed the above error by adding this to chapter 6.6:
ln -s /tools/lib/libstdc++.{so,.6} /usr/lib
I have no idea if this is the correct fix, or if the problem was
somewhere
else. There was no libstdc++* in /mnt/lfs/ or its subdirectories when I
got
to 6.21.
I don't think that's a problem with the fact that you stopped and
restarted - if libstdc++ does not exist in /usr/lib then you forgot to
install the c++ compiler in chap. 6. Does /usr/bin/gcc exist?
No it did not, I noticed this when Groff wouldn't configure complaining that
it couldn't compile c++ programs. There were no gcc or c++ or even cc in
/usr/bin. Very strange, but everyting worked after I installed gcc.
Should I compile ncurces again?
Thanks
Ilja
No, recompiling ncurses won't help if gcc is missing from /usr. Try
checking a couple more things for me...
1. Run the sanity check at the end of the Re-adjusting the toolchain
section and let me know the results.
2. Does /lib/libc.so.6 exist?
3. Does /usr/bin/ar, as, and ld exist?

You said earlier that there was no gcc or g++ in /usr/bin. Do you just reinstall it? I figured out that it was missing while trying to install Groff so I installed it for the first time in chapter 6 (I somehow forgot to install it when it was supposed to be installed). After that everything has worked fine, as I wrote (I'm currently in 6.51) /usr/bin. Very strange, but everyting worked after I installed gcc. checking a couple more things for me... 1.

I have compiled everything after 6.26 according to the book, is there something between 6.14 and 6.27 that has to be compiled using the compiler in /mnt/lfs/usr/? Or is the compiler in /mnt/lfs/tools good enough for packages 6.15-6.26 to be compiled into /usr?
